Is this the Filiform of which I've heard spoken?

I've about stripped all the clear coat and decided to see how the Nuvite products worked. I got F9, C and S.
I did about 30 passes of F9 because I couldn't get it smooth. Then I tried some of the C and this is what I have. Did about 4 passes on an 18" or so section. What's the final word on getting this corrosion compounded out? I'm terrified to use sand paper. Is that my only option?

Try some mineral spirits on a rag and see what happens

Looks like filiform, however....

If you have done that many passes with F9 something is wrong with your polishing. Have you stripped the clear coat off? Are you compounding with a wheel? F9 with just a pad or a Cyclo will not cut thru the clear coat and polish.
Tell us what your doing.....your trailer will sparkle if done right.

Clear coat is definitely off of this part. It's the rear end cap and came off in a sheet with citrus strip.mI'm compounding with a random orbiter with wool bonnets. I went through 2 bonnets with this one spot, spurring them in between, along with in between buffing and wiping down with mineral spirits. So, 5 black rags, 2 bonnets, 2 hours later, this is what I have. Normal?

What kind of random orbiter do you have? You may need to go with a variable speed angle grinder.

I am not a Nuvite expert, it not the only way to skin the cat. I use bar tripoli and rouge and sometimes whatever else is at hand including Mother's Truck Box Polish.

Your photo is not the greatest. A macro photo would help. But it does not look like filiform which is little white wormy squiggly stuff that would have been there from the get go.

It's a porter cable 6" variable speed random orbit sander/ polisher. I decided not to go with the heavier/bigger 7" one because I have arthritis in my elbow. Theses are definitely "scratches" that you can feel with your fingers.

Like I said...THAT type polisher is NOT going to get it done.

I'm afraid I agree. But, even with better equipment polishing takes a lot of work. That's why the pros get thousands of dollars.

The metal is pitted due to time and exposure....corroded.not necessarily filiform though.Which is normally white powder (looks worm like)under the coating.
You will only be able to polish the aluminum so deep and some will not come out.

It seems that, like cars, boats, airplanes, and yes, even myself - something that is getting old simply cannot be made 100% new again. Wear those battle scars with pride!

I was looking to polish a set of wheels last year that looked similar in nature, and found some great information on the web. I presume you have looked at other sites as well, but figured I will post some links to a few that might provide some additional insight. A couple of favorites;

Polishing - Vintage Airstream
Metal Polishing Equipment : Auto Detailing Supplies : Electric Car Polishers : Airplane Polish : Auto Polisher : Aluminum : Polishers and Buffers : PerfectPolish.com

Here is one that goes over the polishing method on some tough looking material
Using the Compounding Polisher : Aluminum Polish : PerfectPolish.com

some info on aluminum corrosion
Corrosion Control For Aircraft

Airstream trailers - Strip and Polish

Scroll down the page about half way to see an article on polishing and AS
Interesting Before & After polishing pictures from Customers and clients

Hope it helps,

Drew
